               return false;
           }
return true
}
$("#getCountButton").click(function () {
            debugger;
            if (!validateValues()) {
                return;
            }

You code looks find. There could be other causes: how did you call this function? Do you have an element with id="batchIDSelect"? Have you include the jquery library? ...

Your code seems fine, but you might be getting a value as 0 or something else instead of a blank value. Change the code to monitor that:
1. Event handler is called.
2. What is the value of batch id.

The modified code is:

JavaScript

function validateValues() {
    alert($('#batchIDSelect').val());
    if ($('#batchIDSelect').val() == '' || $('#batchIDSelect').val() == null) {
        alert("Pls Select the BatchID");
        return false;
    }
    return true
}

$("#getCountButton").click(function () {
    alert("click event handler called.");
    debugger;
    if (!validateValues()) {
        return;
    }
});
